PROCESS FOR PRODUCING PERFLUOROALKYLSULFONIC ACID SALT

In this method for producing a perfluoroalkylsulfonic acid salt, there is provided a method for producing a perfluoroalkylsulfonic acid salt with a low fluorine content, which is a simple method to achieve a high yield, wherein a solution is formed by adding, to at least one compound selected from perfluoroalkylsulfonic acid salts represented by a general formula RfSO3?M (wherein Rf represents a perfluoroalkyl group of 1 to 4 carbon atoms, and M represents Li, Na or K), an organic solvent which is capable of dissolving the compound, and an adsorbent having a capacity to adsorb fluorine ions is added to the solution.

Carbon-chain isomerization during the electrochemical fluorination in anhydrous hydrogen fluoride - A mechanistic study

The compounds i-C4H9SO2F, i-C3H7SO2F and cyclo-C3 H7C(O)F have been subjected to electrochemical fluorination in anhydrous hydrogen fluoride. The resulting products were fully analyzed by NMR spectroscopy. From the reaction balances, literature data and quantum chemical calculations, a new mechanism for carbon-chain isomerization during the electrochemical fluorination (ECF) is proposed. The key step in the formation of isomeric products is believed to be a ring closure reaction involving carbo-cationic or biradical intermediates.
